With legalization of cannabis for medicinal and adult use occurring rapidly at the state level, the industry is seeing a sharp increase in innovative technologies, particularly in the area of cannabis extraction. Companies are developing novel extraction methods that are capable of not only separating and recovering high yields of specific cannabinoids, but also removing harmful chemicals (such as pesticides) from the concentrate. While some extraction methods utilize solvents, such as hydrocarbons, the industry is starting to see a shift to completely non-solvent based techniques or environmentally friendly solvents that rely on, for example, CO2, heat and pressure to create a concentrate. The resulting cannabis concentrate can then be consumed directly, or infused in edibles, vape pens, topicals and other non-plant based consumption products. With companies continually seeking to improve existing extraction equipment, methods and products, it is critical for companies working in this area to secure their niche in the industry by protecting their intellectual property (IP).

Extraction can be an effective form of remediating contaminated cannabis

Comprehensive IP protection for a business can include obtaining patents for innovations, trademarks to establish brand protection of goods and services, copyrights to protect logos and original works, trade dress to protect product packaging, as well as a combination of trade secret and confidentiality agreements to protect proprietary information and company “know-how” from leaking into the hands of competitors. IP protection in the cannabis space presents unique challenges due to conflicting state and federal law, but for the most part is available to cannabis companies like any other company.

Federal trademark protection is currently one of the biggest challenges facing cannabis companies in the United States. A trademark or service mark is a word, phrase, symbol or design that distinguishes the source of goods or services of one company from another company. Registering a mark with the U.S. Patent and Trademark Office (USPTO) provides companies with nationwide protection against another company operating in the same space from also using the mark.

As many in the industry have come to discover, the USPTO currently will not grant a trademark or service mark on cannabis goods or services. According to the USPTO, since cannabis is illegal federally, marks on cannabis goods and services cannot satisfy the lawful use in commerce requirement of the Lanham Act, the statute governing federal trademark rights. Extraction companies that only manufacture cannabis-specific equipment or use cannabis-exclusive processes will likely be unable to obtain a federal trademark registration and will need to rely on state trademark registration, which provides protection only at the state-level. However, extractors may be able to obtain a federal trademark on their extraction machines and processes that can legitimately be applied to non-cannabis plants. Likewise, companies that sell cannabis-infused edibles may be able to obtain a federal trademark on a mark for non-cannabis containing edibles if that company has such a product line.

Some extraction companies may benefit from keeping their innovations a trade secretSince the USPTO will not grant marks on cannabis goods and services, a common misconception in the industry is that the USPTO will also not grant patents on cannabis inventions. But, in fact, the USPTO will grant patents on a seemingly endless range of new and nonobvious cannabis inventions, including the plant itself. (For more information on how breeders can patent their strains, see Alison J. Baldwin et al., Protecting Cannabis – Are Plant Patents Cool Now? Snippets, Vol. 15, Issue 4, Fall 2017, at 6). Unlike the Lanham Act, the patent statute does not prohibit illegal activity and states at 35 U.S.C. § 101 that a patent may be obtained for “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.”

For inventions related to extraction equipment, extraction processes, infused products and even methods of treatment with concentrated formulations, utility patents are available to companies. Utility patents offer broad protection because all aspects related to cannabis extraction could potentially be described and claimed in the same patent. Indeed, there are already a number of granted patents and published patent applications related to cannabis extraction. Recently, U.S. Patent No. 9,730,911 (the ‘911 patent), entitled “Cannabis extracts and methods of preparing and using same” that granted to United Cannabis Corp. covers various liquid cannabinoid formulations containing very high concentrations of tetrahydrocannabinolic acid (THCa), tetrahydrocannabinol (THC), cannabidiol (CBD), THCa and cannabidiolic acid, THC and CBD, and CBD, cannabinol (CBN), and THC. For example, claim 1 of the ‘911 patent recites:

A liquid cannabinoid formulation, wherein at least 95% of the total cannabinoids is tetrahydrocannabinolic acid (THCa).Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.

Although the ‘911 patent only covers the formulations, United Cannabis Corp. has filed a continuation application that published as US2017/0360745 on methods for relieving symptoms associated with a variety of illnesses by administering one or more of the cannabinoid formulations claimed in the ‘911 patent. This continuation application contains the exact same information as the ‘911 patent and is an example of how the same information can be used to seek complete protection of an invention via multiple patents.

An example of a patent application directed to solvent-based extraction methods and equipment is found in US20130079531, entitled “Process for the Rapid Extraction of Active Ingredients from Herbal Materials.” Claim 1 of the originally filed application recites:

A method for the extraction of active ingredients from herbal material comprising: (i) introducing the herbal material to a non-polar or mildly polar solvent at or below a temperature of 10 degrees centigrade and (ii) rapidly separating the herbal material from the solvent after a latency period not to exceed 15 minutes.

Claim 12, covered any equipment designed to utilize the process defined in claim 1.

Although now abandoned, the claims of this application were not necessarily limited to cannabis, as the claims were directed to extracting active ingredients from “herbal materials.”

Other patents involve non-toxic extraction methods utilizing CO2, such as Bionorica Ethics GMBH’s U.S. Patent No. 8,895,078, entitled “Method for producing an extract from cannabis plant matter, containing a tetrahydrocannabinol and a cannabidiol and cannabis extracts.” This patent covers processes for producing cannabidiol from a primary extract from industrial hemp plant material.

There have also been patents granted to cannabis-infused products, such as U.S. Patent No. 9,888,703, entitled “Method for making coffee products containing cannabis ingredients.” Claim 1 of this patent recites:

Despite the USPTO’s willingness to grant cannabis patents, there is an open question currently regarding whether they can be enforced in a federal court (the only courts that have jurisdiction to hear patent cases). However, since utility patents have a 20-year term, extractors are still wise to seek patent protection of the innovations now.

Another consideration in seeking patent protection for novel extraction methods and formulations is that the information becomes public knowledge once the patent application publishes. As this space becomes increasingly crowded, the ability to obtain broader patents will decline. Therefore, some extraction companies may benefit from keeping their innovations a trade secret, which means that the secret is not known to the public, properly maintained and creates economic value by way of being a secret. Properly crafted non-disclosure agreements can help further ensure that trade secrets remain a secret indefinitely.

Regardless of the IP strategy extractors choose, IP protection should be a primary consideration for companies in the cannabis industry to ensure the strongest protection possible both now and in the future.

A number of cannabis businesses have pursued federal intellectual property protection for their cannabis-related innovations, such as U.S. patents that protect novel cannabis plant varieties, growing methods, extraction methods, etc. Enforcement of such federal IP rights requires that the IP owner file suit in federal court asserting those rights against another cannabis company. However, given that cannabis is still illegal under federal law, the industry is uncertain about whether a federal court will actually enforce cannabis-related IP rights. This question might be answered soon.

The potential impact of this case goes way beyond the two parties involvedOrochem Technologies, Inc. filed a lawsuit in federal court in the Northern District of Illinois on September 27, 2017, seeking to assert and enforce trade secret rights against Whole Hemp Company, LLC. According to the complaint, Orochem is a biotechnology company that uses proprietary separation methods to extract and purify cannabidiol (CBD) from industrial hemp in a way that produces a solvent-free and THC-free CBD product in commercially viable quantities.

The complaint goes on to say that Whole Hemp Company, which does business as Folium Biosciences, is a producer of CBD from industrial hemp and that Folium engaged Orochem to produce a THC-free CBD product for it. According to the allegations in the complaint, Folium used that engagement to gain access to and discover the details of Orochem’s trade secret method of extracting CBD so that it could take the process and use it at their facility.

The complaint provides a detailed story of the events that allegedly transpired, which eventually led to an Orochem employee with knowledge of the Orochem process leaving and secretly starting to work for Folium, where he allegedly helped Folium establish a CBD production line that uses Orochem’s trade secret process. When Orochem learned of these alleged transgressions, it filed the lawsuit, claiming that Folium (and the specific employee) had misappropriated its trade secret processes for extracting and purifying CBD.

While the particular facts of this case are both interesting and instructive for companies operating in the cannabis industry, the potential impact of this case goes way beyond the two parties involved.

If it moves forward, this case will likely provide a first glimpse into the willingness of federal courts to enforce IP rights that relate to cannabis. Orochem is asserting a violation of federal IP rights established under the federal Defend Trade Secrets Act (DTSA) and is asserting those rights in federal district court. As a result, the federal district court judge will first need to decide whether a federal court can enforce federal IP rights when the underlying intellectual property relates to cannabis.

If the court ultimately enforces these federal trade secret rights, it could be a strong indication that other federal IP rights, such as patent rights, would also be enforceable in federal court. Since the outcome of this case will likely have a far reaching and long lasting impact on how the cannabis industry approaches and deals with intellectual property, it’s a case worth watching.
